Quote
quote is a Rust crate and macro for constructing Rust token streams from quasi-quoted syntax.
Write Powerful Rust Macros
quote is a Rust library and macro for generating source-token streams from interpolated syntax.
- How it is used
- Generates output TokenStreams for Rust procedural macros, including derive, attribute, and builder macros.
- How deep it goes
- Explains interpolation, repeated field output, TokenStream conversion, testing, and debugging, while deferring compiler token-processing details.
- Examples
- Uses empty macro output, public struct fields, quoted builder expectations, and a generated builder with build and builder methods.
- What you can do after
- Build it from scratch by interpolating parsed Rust syntax into generated TokenStreams and testing the resulting code.
Idiomatic Rust
quote is a Rust library that generates Rust source code from syntax-like interpolation constructs.
- How it is used
- Generates Rust source code within procedural macros through syntax-like interpolation.
- How deep it goes
- Demonstrates interpolation and token stream conversion in a derive macro, but does not explore more elaborate macro features.
- Examples
- Generates a PrintName trait implementation that returns a struct’s name.
- What you can do after
- Apply quote! interpolation to generate code for a Rust derive macro.
